Description

Currently, a new producer needs to be instantiated for each topic that you want to produce to. I am working on a service that intakes messages from many producers, and then sends them on to different Kafka topics based on the content of the message. Instantiating a new producer for each topic is a lot of overhead. It would be handy if there was a way to produce to a topic by specifying topic as a parameter to a produce method.

Research direction
Investigate the current Producer class implementation in pykafka to understand how topics are managed. Review the discussion in the issue comments (#354) for any design considerations and potential approaches. Focus on the produce method and how it can be modified to accept a dynamic topic parameter while maintaining thread safety and consistency with the existing API.
